Reorder Lists & Grids in SwiftUI and Save with SwiftData

SwiftUI's onMove makes reordering lists easy. But that order disappears when the app relaunches — unless you save it.

What this video covers:

• Adding drag-to-reorder to List and LazyVGrid
• Using onMove and onInsert modifiers
• Capturing the new order after drag
• Saving order changes to SwiftData (persistent storage)
• Restoring saved order on app launch
• Handling sections and complex data

Real example: A to-do list, playlist, or dashboard where users can rearrange items and expect their order to stay.
